sthe said frames will be positively held against relative movement in any direction ano held united with a degree of rigidity approximating that which would be laid if the frames were an integral structure, and

of the frames to be connected together, while the other frame is adapted to permit of its being engaged by the vise and rigidly held .ing wheels, one of which is shown and indicated by 6, also the motor 7, the transmission mechanism the casing of which is indicated by 8, an? the various other parts which go. to ma to up an operative tractor some of which are omitted from the drawthis without rendering the device other than ings because of their impertinency to the and the tractor frame with a female member adapted for receiving the male member, rendering one of these members movable with respect to the other, and adapting each to interlock with the other when the movable member is moved in one direction.

Other objects will appear anti be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, in which Figure 1 is a contracted side elevation partly in section of a tractor and a load carrying vehicle showing my invention partly in section and in elevation and connecting the tractor and the load carrying vehicle. Fig. 2 is a detail cross section taken approximately on the line i-2 of Fig. 1. Fig. 3 is a detail plan of the female part of the connector. Fig. at is a side elevation partly in section of the element shown in Fig. 3.

present invention, and others of which are shown such for instance, as part of the steering mechanism," the wheel of which is shown and indicated by 9.

- The rear ends, of the sides 1010 of the tractor frame are connected by an end piece 1.1 which may be formed integral with the sides'oiflotherwise suitably connected there with. This end piece forms one component or jaw of the vise or female member. The other component or jaw of the -"female member is indicated by 12 and is mounted for movement on the plane surface of a. bearing plate 13 which is formed integral or otherwise suitably connected to the sides 1010. Suitable mechanism such as a screw 14, is employed .for moving the jaw' 12 toward or away from the jaw 11. This screw is mount ed in bearings 15 and 16 arranged intermedilate of the ends of the jaws 11 and 12 and in alinement one with the other. One of these bearings, such as the, bearing 16, is threaded to coiipera-te with the threaded portion 17 of the screwv 11. The outer cndof the screw is provided with a non-cylindrical head 18 constructed so as to take a wrench or other suitable tool for .turning the screw 14 to operate the jaw 12. As shown this head 18 is at the rear end of the tractor frame, and by virtue of this position access may be readily had thereto by an operator positioned below the frame of the load carrying vehicle and at the rear end of the tractor frame. It will be noted that the bearing plate 13 is ositioned a trifle below i the upper surfaces f the sides 1010 of 'the a tractor frame so that those portions of the iii) sides extending above the plate 13 will func tion as guides for the movable jaw 12, the ends of which bear on, the said projecting portions of' the sides." Devices for supplementing the screw 14 toTprevent upward tilting or displacement of the movable jaw 12, are provided and maybe of any suitable the load carrying vehicle or suitably connected thereto, such as by pins 22. In its construction the male member includes a head "23 which is located well within the plane of the frame of the load carrying vehicle b so-that when this frame is connected to the' frame of the tractor the sides thereof may bear on the sides of the tranieof the I and igmay one 5 present to the other a maximum of bearing surface consisted with the width of head and the length of aw desirable in a connection of this kind; the said order that the head tractor a, or substantially so. The head may beformed iii-any suitable manner, such asv "by forming longitudinal recesses 24 -24 in the lower face and ad acent to the opposite sides of the male member 0. j

23 and the jaws 11 jaws are formed'substantially V-shaped in contour and the ends of the headare shaped to correspond to the jaws. As will be noted by reference to Figsf, to l inclusive, the jaw 11 projects beyond the upper surface of 1 the sides 10-10 of the'tractor frame and is groovesQEF-ZG are appreciably shorter than thefioorsof the grooves, thus ledges 29-29' shown in Fi 3, are provided for holding the tongues 24-27 centered with'the grooves prior to adjusting the said tongues in the said g'rgioves. By reason of the peculiar slopes of the jaws 11 and 12 and the contours'of the ends of the head 23-together with the presence of the grooves, 25 and 26 and tongues 27 and 28, it will be manifest that when the head 23 is"'-vised as shown in PE 1, lateral displacement of thesaid head or lateral vibratory movement thereof will be positively prevented, while vertical vibratory movement will be prevented by the presence of the beveling 30 on the bearing surfaces of the head and the overhanging parts of the jaws 11 and 12 as shown 'in Fig. ,6. In this connection. it will be noted that the beveling 30 also operates to practi- 31 formed in the under side of the head, re-

ceives the screw 14 as shown in Fig. 2. In 'adjusting thehead the tongues 27 are placed on the bottoms of the grooves 25 afterwhich the screw 14 is turned with a suitable implement in a direction so as to move the jaw 12 I toward the jaw 11. This movement on thepart of the jaw 12 is continued until the cally eliminate torque on the tongues 27 several tongues are completely nested within the grooves 25 and 26 and the bevgd surfaces 30 in contact one. with the other. After which suitable nuts or e uivalent locking deq vices 32 are applied to the end of the screw to prevent accidental turning movement thereof. a

What is claimed as new is: v p v 1. In combination with the overlapping end portions. of a load carrying vehicle frame and a tractor frame; of-nieans for connecting the said overlapping end portions together and including a movable jaw carried by one hit said; end portions, and a head carried .hy'the other of said end por tions, said jaw and said head being further adapted to interfit and to interlock one with the other when the movable jaw is adjusted into one position and to disengage one from he other when the movable jaw is adjusted into another position. 1 2. ,Means for connecting together the overlapping end portions of a tractor frame and 'a load carrying vehicle frame, and comprising a pair'ofmembers carried by the said overlapping end portions, said members be ing constructed and arranged so as to inter- 'tionary and the other movable, and means for adjusting the movable jaw member with respect to the stationary jaw member for the purpose set forth.
